【Abstract】 The flavoring compounds of fresh Iris rhizomes treated by biological technology were prepared with simultaneous distillation and extraction equipment(SDE).They were isolated and identified by capillary GC/MS method.69 volatile components were identified and determined,accounting for 84.24% of the total area of the peak.The relative contents of constituents were determined by area normalization method.The main flavoring compounds are:3-methyl-2-butenal(0.14%),(Z)-3-hexenal(0.09%),(Z)-2-heptenal(0.07%),(E)-2-decenal(0.08%), (E,E)-2,4-decadienal(0.06%),octanoic acid(0.52%),n-decanoic acid(0.66%),dodecanoic acid(0.57%),2,4-dihydroxy-3,6-dimethylbenzoic acid(0.13%),tetradecanoic acid(7.76%),pentadecanoic acid(0.19%),1,2-benzenedicarboxylic acid(0.14%),9-hexadecenoic acid(0.37%),n-hexadecanoic acid(11.25%),heptadecanoic acid(0.21%),(Z,Z)-9,12-octadecadienoic acid(26.09%),(E)-9-octadecenoic acid(9.58%),artemisia alcohol(0.20%),cyclonerolidol(0.88%), 1-docosanol(0.20%),2-(tetradecyloxy) ethanol(0.15%),3,7,11-trimethyl-2,6-dodecadien-1-ol(0.08%),artemisia ketone(0.04%),1-(4-hydroxy-3-methoxyphenyl)ethanone(2.69%),4-(2,5,6,6-tetramethylcyclohex-1-en-1-yl)butan-2-one(0.12%),5-methyl-α-ionone(1.22%),1-(3,4-dimethoxyphenyl)ethanone(0.47%),3,5,5-trimethyl-2-cyclohexen-1-one(0.16%),1-(4-hydroxy-3,5-dimethoxyphenyl)ethanone(0.16%),ethyl tetradecanoate(0.20%),ethyl hexadecanoate(0.53%),δ-nonalactone(0.29%),methyl 10-octadecenoate(0.49%) and bis(2-ethylhexyl) phthalate(1.47%).更多还原
